+# Codex CLI
+
+Delegate coding tasks to [Codex](https://github.com/openai/codex) via the Hermes terminal. Codex is OpenAI's autonomous coding agent CLI.
+
+## Prerequisites
+
+- Codex installed: `npm install -g @openai/codex`
+- OpenAI API key configured
+- **Must run inside a git repository** — Codex refuses to run outside one
+- Use `pty=true` in terminal calls — Codex is an interactive terminal app
+
+## One-Shot Tasks
+
+```
+terminal(command="codex exec 'Add dark mode toggle to settings'", workdir="~/project", pty=true)
+```
+
+For scratch work (Codex needs a git repo):
+```
+terminal(command="cd $(mktemp -d) && git init && codex exec 'Build a snake game in Python'", pty=true)
+```
+
+## Background Mode (Long Tasks)
+
+```
+# Start in background with PTY
+terminal(command="codex exec --full-auto 'Refactor the auth module'", workdir="~/project", background=true, pty=true)
+# Returns session_id
+
+# Monitor progress
+process(action="poll", session_id="<id>")
+process(action="log", session_id="<id>")
+
+# Send input if Codex asks a question
+process(action="submit", session_id="<id>", data="yes")
+
+# Kill if needed
+process(action="kill", session_id="<id>")
+```
+
+## Key Flags
+
+| Flag | Effect |
+|------|--------|
+| `exec "prompt"` | One-shot execution, exits when done |
+| `--full-auto` | Sandboxed but auto-approves file changes in workspace |
+| `--yolo` | No sandbox, no approvals (fastest, most dangerous) |
+
+## PR Reviews
+
+Clone to a temp directory for safe review:
+
+```
+terminal(command="REVIEW=$(mktemp -d) && git clone https://github.com/user/repo.git $REVIEW && cd $REVIEW && gh pr checkout 42 && codex review --base origin/main", pty=true)
+```
+
+## Parallel Issue Fixing with Worktrees
+
+```
+# Create worktrees
+terminal(command="git worktree add -b fix/issue-78 /tmp/issue-78 main", workdir="~/project")
+terminal(command="git worktree add -b fix/issue-99 /tmp/issue-99 main", workdir="~/project")
+
+# Launch Codex in each
+terminal(command="codex --yolo exec 'Fix issue #78: <description>. Commit when done.'", workdir="/tmp/issue-78", background=true, pty=true)
+terminal(command="codex --yolo exec 'Fix issue #99: <description>. Commit when done.'", workdir="/tmp/issue-99", background=true, pty=true)
+
+# Monitor
+process(action="list")
+
+# After completion, push and create PRs
+terminal(command="cd /tmp/issue-78 && git push -u origin fix/issue-78")
+terminal(command="gh pr create --repo user/repo --head fix/issue-78 --title 'fix: ...' --body '...'")
+
+# Cleanup
+terminal(command="git worktree remove /tmp/issue-78", workdir="~/project")
+```
+
+## Batch PR Reviews
+
+```
+# Fetch all PR refs
+terminal(command="git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'", workdir="~/project")
+
+# Review multiple PRs in parallel
+terminal(command="codex exec 'Review PR #86. git diff origin/main...origin/pr/86'", workdir="~/project", background=true, pty=true)
+terminal(command="codex exec 'Review PR #87. git diff origin/main...origin/pr/87'", workdir="~/project", background=true, pty=true)
+
+# Post results
+terminal(command="gh pr comment 86 --body '<review>'", workdir="~/project")
+```
+
+## Rules
+
+1. **Always use `pty=true`** — Codex is an interactive terminal app and hangs without a PTY
+2. **Git repo required** — Codex won't run outside a git directory. Use `mktemp -d && git init` for scratch
+3. **Use `exec` for one-shots** — `codex exec "prompt"` runs and exits cleanly
+4. **`--full-auto` for building** — auto-approves changes within the sandbox
+5. **Background for long tasks** — use `background=true` and monitor with `process` tool
+6. **Don't interfere** — monitor with `poll`/`log`, be patient with long-running tasks
+7. **Parallel is fine** — run multiple Codex processes at once for batch work
